Great Part

Speedy delivery; part fit perfectly.

Guest - November 19, 2019 Verified Purchase

Got the part in record time.

This spark plug was for an older model Honda MANTIS cultivator. 20 years old and in storage for years. Just to be thorough, put in a new plug..... started right up. (Had to replace the primer bulb at the same time. Which your service also provided!) Thank you, Tom

Thomas - October 21, 2019 Verified Purchase

Always easier with right parts!

Everything matched what I was replacing and the "parts " sheet on the site made me realize I was actually missing a few things. Glad for that and started right up.

GEORGE - October 16, 2019 Verified Purchase

Excellent parts, perfect fit.

All parts ordered were exact replacements packed in pristine condition and fit perfectly. My trimmer is running again after years of disuse.
